The Princess and Curdie [EPUB ebook] 

Princess Irene and her father go to Gwyntystorm, while Curdie stays at home with his mother and father. As the years go by, Curdie begins to hunt for pleasure. He also slowly begins to doubt Irene’s story of her great-great grandmother. One day, he shoots down a white pigeon. Curdie then remembers Irene’s tale of her grandmother’s pigeons, assumes the one he has shot down was one of them, and becomes aware of his folly. A light appears at the roof of the castle, and Curdie follows it. There, Curdie meets the old Princess, who appears small and withered, contrary to Irene’s descriptions.
